“…In recent years, the rapid development of new advancements requires communication systems to generate newer ways of increasing the bandwidth and capacity of channels. For this purpose, the optical system is probably the best technique which can fulfil requests for high data rate and significant transmission distance [1, 2]. This system of communication is based on the line of sight, so any hindrance between the transmitter and the recipient cannot be ignored.…”

With the growing demand for usage among Internet users, inventions related to increase in the capacity and bandwidth of transmission channels are more significant nowadays. This continuously growing demand can be fulfilled by using the optical fibre for transmission of signals instead of the wireless mode of transmission, due to the less nonlinearity present in the optical fibre. As every available mode has its own shortcomings so does the optical fibre. It suffers from dispersion and other linearities when long-distance transmission is considered. Hence, the field of invention is associated with the compensation of dispersion in optical fibre communication at higher bit rates of 50-80 Gbps for longer distances of 120 km. After their compensation, comparison of two photodiodes, that is, pin diode and avalanche photodiode has been done at these distinct bit rates in order to achieve the best suited photodiode. After the complete analysis of simulations in terms of quality factor and bit error rate, it has been observed that at distinct bit rates of 50-80 Gbps, the simulation model using avalanche photodiode exhibits superior performance to that of the pin diode. The comparison results show that the performance of the avalanche photodiode is around 11% better than the pin diode.This is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited.

In order to ensure that the steel structure of the building can meet the requirements of the strength of the building structure and the strict requirements in the fields of earthquake resistance, fire protection, energy saving, and environmental protection in the construction process, a method based on virtual reality supply chain cloud computing collaborative management technology is proposed. This method analyzes the main technology of building steel structure and establishes personalized cloud computing collaborative management technology based on virtual reality supply chain. Based on the analysis of industry characteristics and personalized service characteristics, the virtual reality control mechanism of personalized data mining is proposed by considering the service time cost and user experience quality. Based on cloud computing and VIRTUAL reality GIS, a collaborative management and control system architecture is proposed to optimize user personalized needs and solve the impact of differentiation on the supply chain. Experimental results show that compared with the noncollaborative management scheme, the collaborative management algorithm proposed by this method reduces the interference of personalized differences on supply chain management by 25%. The experimental results show that this method can greatly guarantee the satisfaction of steel structure construction process.

“…In optical networks, the S-band comparably shows better attenuation characteristics and is less prone to bending losses [8]. The chromatic dispersion arising in CSMF by launching S-band lies in the range of 12 to 16 ps/nm/km [13], which is approximately 10-30% less dispersion than the other two bands.…”

1.28 Tbps DWDM optical network design using a dispersion compensating distributed Raman amplifier over S-band

A 100 km long dense wavelength division multiplexed optical network design with a capacity of 1.28 Tbps is proposed in this paper. The novelty of this work is the use of a dispersion compensating fibre as a Raman amplifier in the S-band for a high-capacity dense wavelength division multiplexing network. The transmission is accomplished auspiciously in the wavelength range from 196 THz to 202. 35THz. The coupling of a Raman amplifier made the realisation of the S-band possible in the network, as the erbium-doped fibre amplifier is competent for amplification in C-and L-bands only. Further, a pump coupler is used for multiple pumping to enlarge the gain spectrum for a high-capacity optical network. The performance analysis of the network is carried out systematically in terms of bit error rate (BER), eye diagram, Q-factor, and optical signal to noise ratio (OSNR). The results demonstrate that the proposed set-up shows adequately low BER, sufficient Q-factor values, wide eye-opening, and commendable OSNR for all receiving channels.
